FFMpeg - gold standard for all OS versions.

Likely SOX also has a port done for Windows. Unsure, as I only use OSX + Linux.

If you're only doing this once with a single set of .mp3 files, use Audacity, which runs on every OS.

If this task repeats continually, then scripting an FFMpeg will likely be better.

Can't you just say?
copy *.mp3 combined.mp3

Open in new window

@Shaun Vermaak

I could have, but it would have been totally wrong.  Did you try your suggestion before posting it?  I suggest that you do so.

It is the + symbols in the COPY command between the file names that makes it step through the named files appending them to the previous ones in the sequence specified.

copy "a.mp3"+"b.mp3"+"c.mp3" "joined.mp3"

will append B to the end of A then C to the end of AB so you end up with ABC.  The reason I mentioned in my other question comment about the resultant MP3 not being completely compliant with MP3 standards is that the combined file will still have all the original MP3 tags for each of the source files in it where each of them were appended.

The only reason this works with MP3 files is because they have a fairly simple structure of sequential "frames" and MP3 players generally ignore the fact that the combined MP3 will have repeated ID3 tags (MP3 tags).  That kind of appending copy command won't work on most other kinds of files other than plain text.

Must be all the same bitrate.  You need to open separate files and cut and paste to join them together.

In my country ? means a question
I know what a question mark is.  It is a character used universally throughout the Western world.  In Spanish (Catalan and Galician), since the second edition of the Ortografía of the Royal Academy in 1754, a second interrogative inverted question mark precedes the question.   Basque, however, only uses one question mark.  In Unicode an upright standard question mark, sometimes also known as an interrogation point, a query, or an eroteme in journalism, is encoded at U+003F.   The ASCII code is 63 (0x3F hexadecimal). The HTML code for it is ?

Anyway, I need to correct my earlier command.  The  /b   switch means "treat files as binary" as opposed to the default of /a meaning ascii (text) file.  The command for MP3s would therefore be:

copy /b "a.mp3"+"b.mp3"+"c.mp3" "joined.mp3"

And this command works perfectly so my suspicion was correct.
copy /b *.mp3 combined.mp3

Open in new window

It just did not have the /b because your accepted answer didn't. I assume you pasted it without testing and corrected in a subsequent comment.
Thank you Knowledgeable
